SSIS Package 2008 - Column Has A Null Value
Aug 10, 2011
I am currently working on an SSIS package that we are migrating from SSIS 2005 to SSIS 2008. The issue is that the developers of the current version used the fact that in SSIS 2005 the accessor of a NULL column returns 0, whereas SSIS 2008 throws an exception. Also, they extensively use expressions such as this one:
IIf(Row.X_IsNull, System.DBNull.Value, Row.X)
The problem is that in SSIS 2008, regardless of whether the condition is set to true, the program still tries to read Row.X and throws an exception. The package is big and it would take a very long time to convert all of these IIfs to manual Ifs with temporary variables.

I created a simple VB application in Visual Studio 2010.My computer, which I am using to create the program, is Windows 7 Pro, and SQL Server 2008 is running on a Windows Server 2008 Enterprise, which I have full access to.
I want to click a button and have an SSIS package execute.I looked around on the Internet and found examples, but they do not seem to work for me.I try to add a reference, Microsoft.SqlServer.ManagedDTS.dll, as a few sites advise, but it is not listed when I go to PROJECT>ADD REFERENCE.
I also type:
Imports Microsoft.SqlServer.Dts.Runtime but all I get is a squiggly green line, which when hovered over states "Namespace or type specified in the Imports 'Microsoft.SqlServer .Dts.Runtime' doesn't contain any public member or cannot be found." Below is some code I copied from one of the websites and pasted in my button click event (the path is correct), but a get blue squiggly lines under "Package" and "DTSExecResult":
Dim pkgLocation
As String
Dim pkg As
New Package[code]....
What can I do to make the SSIS package run when I click the button on the Windows application a created?

My DBA has several SSIS packages that he would like the functionality of providing the end user with a way to input values for variables in the package. What would be the best solution for creating an application that would take the user input and pass the data through to the SSIS package variables?
I can get this work locally using this code
Dim packageName As String
Dim myPackage As Package
Dim integrationServices As New Application
[code]....
Problem is this requires that the user have SSIS installed locally.

The specified package could not be loaded from the SQL Server database ssis package is working fine from BIDS as well as from SQL Server Management Studio (SSMS).Package is deployed to the File System of SSMS.I am using the following code.
Code:

I've had to backwards convert my SSIS 2008 package to 2005 including converting all the C# script tasks to VB. After finishing this and getting it to run fine from Visual Studio, I went to deploy it to the server but when I import the package through SSIS into the 'File System' I get the following error:[code]Now when I open the package file up and go to that line this is what I have:[code]

I have created an SSISpackage in my asp.net project.To call the ssis package, i have written the following code.
dim app as new Application()
dim package as Package=app.LoadPackage("C:ProjectsMyPackage.dtsx")
dim result as DTSExeResult=package.Execute()
Response.Write(result.Tostring())
but it shows some errors.i think some namespaces are missing.What all namespaces have to be imported?

I have successfully run an ssis package and inserted data from one table in the first database to another table in the second database. But all the rows are inserted in this case. I have placed an oledb source control, a character map control and an oledb destination control. No query is written in this. I specified only the source table and the destination table in the 2 databases. But I need to transfer only some column values in one table to another, not the entire table data.

i am writing a VB front end (VS 2008 .NET 3.5) to a data loading program that involves moving the contents of CSV flat files into SQL Server 2005 staging tables. I have had some experience with DTS in SQL 2000 so I decided to use SSIS packages to load the CSV data. Creating the packages in BIDS worked fine for the development environment where I hard-coded the Connections and file paths. The problem arises when I will release this program to 30 different sites that do not have SQL Server admins to help changing the configuration.
I have a SQL table in which I will put all the necessary path information and I can pull that into the VB program on startup. I need to see an example of how I can set the properties from VB once the package is instantiated and opened.Here is an example of where I plan to set those properties and run the packages.
Private Function RunPackages() As Boolean
Try
Dim oApp As New Application
Dim oPackage As New Package
[code]....
Even though I am using a configuration file in the example, I am finding it difficult to edit the configuration files for each site. I see that there are methods and properties exposed for the oPackage instance. However, I can't find a good reference for the Class model to use as a guideline. All the examples expect packages to be run and configured with SQL Server and BIDS. direct manipulation of package properties in VB or C#?I am now considering using the old standby SQL Bulk Insert. It almost appears as if the Data Tasks are just wrappers for the Bulk Insert operation. Furthermore we have several sites still using SQL Server 2000. With the economy the way it is, most of those sites do not want to spend ANY extra money upgrading to SQL 2005 or 2008.
However, having a good resource to learn how to manipulate SSIS packages from the CLR would be very helpful. I have heard that in SQL 2008 things have changed even more. It is maddeneing that once I learn a "new" Microsoft technology it seems to be discarded by MS in their next release in favor of a "better" alternative.

I am using VB.NET 2002 and we have set up a test environment running SQL Server 2005. I am trying to add a reference to Microsoft.SQLServer.ManagedDTS.dll which is required to run a DTS/SSIS package from VB.NET. However the dll does not show in my add reference listing so when I select BROWSE and select the actual DLL I get a rather long error message telling me that only 'dll' and COM components can be referenced.
The exact message is: A reference to 'C:Programs FilesMicrosoft SQL Server90SDKAssembliesMicrosoft.SQLServer.ManagedDTS.dll' could not be added. This is not a valid assembly or COM component. Only assemblies with extension 'dll' and COM components can be referenced.make sure that the file is accessible, and that it is a valid assembly or COM component.

I am connected to a MYSQL database and the following Insertcommand works fine:
InsertCommand="INSERT INTO suppliers (Supplier) VALUES (?Supplier)"
Now when I want the option of updating all the columns it keeps saying "Column 'Contact_2' cannot be null" or contact_1, so all the fields need something and not all suppliers of course have two numbers. What am I doing wrong? here is the
InsertCommand="INSERT INTO suppliers (Supplier, Contact_1, Contact_2) VALUES (?Supplier, ?Contact_1, ?Contact_2)"

When I put a break point to the last if clause in the sub ("If (backOrder < 0) Then", see below) it runs until the break point, if I put the break point further below, I get the following error:
Cannot insert the value NULL into column 'OrderID', table 'WHM.dbo.OrderDetails'; column does not allow nulls. INSERT fails. The statement has been terminated.
I've discovered first hand that it only happens when prodqty is bigger then qtyOnStock, thus executing the if clause.

Private Sub NCOSubmit_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles NCOSubmit.Click

I used to develop applications in VBA, but now I'm using SQL Server 2008 Integration Services for a lot of the functionality, and using VB.NET as the scripting language where needed - all of which are new to me. I need to do the same string manipulation in several different SSIS tasks. With VBA, I'd simply write a function and declare it Public, and I could use it from any module. E.g.
Public Function MakeId(ByVal Country As String, ByVal Postcode As String) As String
....
End Function
' later...
Dim MyId as String
MyId = MakeId(County, Postcode)
But when I do that in a Script Task or Script Component, I find I can't call the function from VB in any other Script Task or Component; it says MakeId is undeclared. It works within its own 'box', but not from anywhere else.

I have a databound DataGridView and use a button to control updates.
The problem is that if a db Column does not allow a null value an error is thrown ("Column <ID> does not allow null values") and then the datagridview automatically removes the row. This error is raised as soon as the user leaves the cell and before the update command is issued.

Using VS2005, VB.Net, Dot Net 2.0, SQL Server 2000. If have some Columns (varchar and numbers) in a DataRow that I want to set to DBNull in the database. The fields as defined as Nullable in SQL DB table.
I have some fields that are populated when loaded but I want to update to be null using the ADO.Net data objects. If I try and use Row("FieldName") = DBNull.Value a 0 gets written to number fields (not sure what gets written to varchar fields.) What code should be used to update fields to Null using ADO.Net dataobjects?

I am using VB.net within Visual Studio 2008. I currently have GridControl where one of the columns fetches a real number from the database. Whenever I try to remove the value I get a red 'X' saying that the input string is not the right format even though I know it can display null because the row underneath fetched a null value for that column.

I am using VB2008 on Win XP SP3 and an relatively new using this language. I would like orientation or advice on how to proceed given the following:I execute an SQL statement, such as select * from MyTable where FieldX='aaa'An exception happens. Now I need to attempt to determine what went wrong:1. Cable was cut2. Syntax error in SQL3. PC where SQL Server is running crashed4. Timed outI need to attempt to recover from this issue. I have basically 2 options: It is a glitch that self corrects after a period of time, so I can just go ahead and retry the operation a few times. Option 2: It is something permanent, so no matter how many times I retry, the error will persist.
